Kevin,
I agree with this totally. I don't believe a plants genera or specific hybridizing
makes it more susceptible to bacterial infections than any other. A plants
immune system is pretty much affected by its cultural environment. Wet
environments, low light levels and high moisture can all favor bacterial
emergence. Since the primary two bacteria (Erwina & Pseuodomonas) that
affect orchids are water borne, they can easily be transported by splashing
or moving water, contact between plants, and contaminated media as well
as carried by insects and other organisms. Thus maintaining the best
cultural care, including using sterile techniques when cutting and repotting,
can eliminate their immune system being jeopardized.
